IMPROVEMENT IN STEAM-ENGINE CIL-(mrs.l

TO ALL 'WHOM IT MAY CONCERN':

Be'it known 'that I, .MOSES HAWKINS, of Birmingh am; of the county ot` New Haven, in the State of Conncctieut,.have invented a new and useful Oil-Cup forSteam .Engines land I do hereby declare that the following is a full and exact description thereof, refercnee being had to the accompanying drawings, making part of this application.

My invention relates to a novel method of constructing 4au oil-cup vflor steam cylinders, and has for its object to effect the feeding iu ot' the oil automatically by the action of 'steam,'in a manner'to be presently explained, and to vthis end my invention consist-s in a novel mode of constructing oil-cups, in which the lubrieating material therein contained is liftedby condensed steam4 and allowed'to flow over into and down through the steam tube into the cylinder, as hereinafter more fully described.v

ToA enable those skilled in vthenrt to. make and use my invention, I will proceed to describe it-'more.fully, referring by le'tters to theaccompanying drawings, in which I have' shown'in vertical section one of my new oil-cups. l

A is the body of the oil-cup, which may be madeof any shape convenient to contain the oil or otherplullni` cater, and the hollow stem or neck B of 4which is provided with a cocl: or valve, G. From the upper portion of the stem B (orbottorn ofl cup A) extends upward, nearly 'to the top edge of cup A, a tube, D, the-function of Vwhich willbe presently explained. E'is'va cap .or cover, which is screwed .onv thc upper edge ofncnp A, as shown, and which is removed and replaced whenever it is necessary to replenish-the lubrica'tor. j" is the waste cock 4through which the cup is emptied, as will be presently explained. i

In the drawing, the cupA is illustrated as it' about half exhausted of its full'jallowance ot' oil; the space lined with blue illustrating water, lthat lined with red, oil.

- The operation of an oil-cup constructed` as described may be thus explained :k The stem-B being secured to the steam engine in the ordinary manner, and the cock or valve C turned so as to cutoff-communication between the cylinder and cup A, the latter is lled with oil, (or other lubricating materiah) and its lid E screwed on tiglift, and the cock closed. To 'effect a supply of oil to the cylinder, the cock C is turned, as seen in the drawing, so as to. admit steam into the oil-cup. The steam passes up throughthelcentral tube D, and'escaping v therefrom is allowed `to condense inthe body A, when it descends. in the form o'water to the" bottom of the cup A,'dis'p'lacing a given amount of the oil, which rises and owsdown the tube D into the `cylinder. In this manner thecylindcr is oiled as llonglas' the oil lasts, and when the supply is exhausted, andthe cup A becomes full of water, (condensed steam the cock C being closed, the wastetcockfis Opened7 the vater dlvwn om :md the eup A refilled with oil. It tallow or other congealed -or solidified grease be used the action nf the steam will melt and feed in the same in the manner' explained of the oil.

Having explained the construction and operatiorrot' my new oil-cup so that oneskilled in the art'can make and use'the same, and being'aware that oil-cups have been heretofore made in which the oil was'fed in/by7 displacement effected by condensed steam, what I claim as new,.and desire to secure by Letters Patent, is-

An Oilfcup A,`provided with a stand pipe D, extending up to near the cap E, and a water-cockf, the whole constructed and operating as described. y l 1 v In testimony whereof I havehereunto 'set my hand and seal this.26th day of November, 1866.
